LAMP-SHADE HOLDER.

Specification of Letters Patent.

Application filed April 8. 1913.

atented Mar. 17, 1914. Serial No. 759,640.

To aZZ whom it may concern:

Be it known that I, FREDERICK WV. Wh minnnn, a citizen of the United States, and a resident of Vermilion, county of Erie, and State of Ohio, have invented a new and useful lmprovement in Lamp-Shade Holders, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have coiniemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is a new and improved means for attaching a shade holder to a lamp socket, and is particularly adapted for use where the lamp socket is supported vertically and the shade .holder must therefore be supported from the lamp socket.

The usual means for attaching a shade holder to a lamp socket are clumsy and difficult to manipulate, and the present invention has been designed with a view to avoiding 'hese dilliculties and to providing a sin1- ple and eilicient mechanism for connecting these two members.

To the accomplishment of these and relatcd ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of Various mechanical forms in which the principle of the invention may be used.

In said annexed drawing: Figure 1 is a plan view of a shade holder attached to a lamp socket by my improved means; Fig. 2 is a vertical section through the device shown in Fig. 1 on the line 22 in such figure; Fig. 3 is a plan View showing a portion of a shade holder and lamp socket with a modified construction of attaching means; F ig. i is a section on the line 4ll in Fig. 3; and Fig. 5 is a perspective View of such modified attaching means.

In Fig. 1 there is shown a lamp socket 1 of the usual construction, and a shade holder 2 which is provided with a central aperture 3, the walls of such aperture being rounded at their upper portion 4;, thus adapting such aperture to receive the lamp socket, a flange 5 which is formed on the lamp socket contacting the rounded portion 4 of the walls of the aperture thus preventing entrance of the socket into the aperture beyond a certain point. Movably mounted upon the shade holder adjacent to the aperture are retaining means which will preferably consist of rotatable disks (3 provided with an eccentric portion 7 which is adapted in a certain position of the disk to register with the wall of the aperture 3, thus permitting a free entrance of the socket into the aperture. When the socket has been thus engaged, the disks (3 are rotated slightly, thus bringing the larger portion of the disk over ti 5 aperture and into contact with the upper side of the flange 5 on the socket, thus locking this flange between the rounded walls of the aperture and the disks, and preventing disengagement of the socket from the shade holder.

The particular form which the retaining means may take, is not of prime importance, and I show two forms which may be used with equally good results. The first of these forms is shown in .lfiigs. 1 and 2, and consists of the rotatable disk (3 provided with an extending portion 1-lwhich may be grasped by the fingers to manipulate the disk. The second of these forms is shown in Figs. 3 and l, and also consists of a disk 6 provided with a notched portion 8, the metal strip 9 which is cut out to form the notch being bent up to form a handle which is similar in function to the extension shown in the previously described form. In the path of movement of the extension 1 1- in the first form, there is provided a button 10 which is preferably stamped out from the shade holder, and is adapted to be friction ally contacted by the extension 1-flwhen the disk is being rotated, thus permitting the extension to pass over it with dillicully and tending to prevent disengagement of the disk from its locking position. lVhen a disk of the type shown in Figs. 8 and at is used, the button is so disposed with relation to the disk that when the latter is brought into its locking position the notch 8 in the disk will register with the button, thus prc venting accidental movement of the disk into its open position.

The present improvement is not only conveniently manipulated but is so formed that it is not unsightly and does not detract from the general appearance of the fixture as do so many of the devices which have been designated to serve the same purpose.

ther modes of applying the principle of my invention may be explained instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the tolloiving claims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim as my invention 1. The combination of a shade holder of substantially standard type adapted to receive a lamp socket of substantially standard construction; and rotatably mounted disks on said shade holder adapted to engage said socket and prevent disengagement of the same.

2. The combination of a shade-holder of substantially standard type adapted to receive a lamp socket of substantially standard construction; rotatably mounted disks on said shade holder adapted to engage said socket and prevent disengagement oi": the same; and means adapted to retain said. disks in operative position.

8. The combination of a shade holder having an aperture adapted toreceive a flanged lamp socket, the Walls of such aperture being rounded at the top to contact with the flange on said socket; and an eccentric disk rotatably mounted on said shade holder and adapted to engage above such flange on said socket thereby preventin disengagen'ient of said socket from said shade holder.

4. The combination of a shadeholder having an aperture adapted to receive a flanged lamp socket, the Walls of such aperture being rounded at the top to contact with the flange on said socket; eccentric disks rotatably mounted on said shade holder and adapted to engage above such flange on said socket, thereby preventing disengagement of said socket from said shade holder; and means adapted to retain said disks in operative position.

5. The combination of a shade hold-er having an aperture adapted to receive a flanged lamp socket, the Walls of such aperture being rounded at the top to contact With the flange in said socket; a locking disk pro vided with an extension, said disk being rotatably mounted on said shade holder adjacent such aperture and being adapted to engage ab ve such flange on said socket thereby preventing disengagement of said socket from said shade holder; and a projection extending into the path of movement of such extension and permitting the latter to pass over it with difliculty, thereby tending to prevent movement of said disk from its operative position.

Signed by me, this 3rd day of April, 1913.
